Phytoplankton adaptation to marine ecosystems: insights into photophysiological functional diversity [PDF]

, 2011
The aim of this study was to investigate the diversity of the photoprotective responses activated by phytoplankton at short temporal scales, i.e. the non-photochemical quenching of Chl a fluorescence (NPQ) associated with the xanthophyll cycle (XC ...

Static and dynamic bimolecular fluorescence quenching of porphyrin dendrimers in solution

, 2008
The fluorescence quenching kinetics of two porphyrin dendrimer series (GnTPPH(2) and GnPZn) by different type of quenchers is reported. The microenvironment surrounding the core in GnPZn was probing by core-quencher interactions using benzimidazole.

Toward Development of Fluorescence-Quenching-Based Biosensors for Drought Stress in Plants

, 2019
Abscisic acid (ABA) is a drought stress signaling molecule, and simple methods for detecting its levels could benefit agriculture. Here, we present proof-of-concept detection for ABA in aqueous solutions by the use of a mixture of Cyanine 5.5 (Cy5.5 ...
